Principles of Visual Perception - Proximity (MaxFactor)
At any given moment, vast amounts of visual stimuli enter the eye—far more than we can pay attention to. The brain selects and organizes visual information according to a number of visual perceptual principles.
The law of proximity states that when an individual perceives an assortment of objects they perceive objects that are close to each other as forming a group. In other words ,When the individual parts of a stimulus pattern are close to each other, we tend to group them together as a meaningful ‘whole’—a single unit.
